How did the 1815 eruption of Tambora in Indonesia indirectly lead to the first widespread cholera epidemic?单项选择题
Aerosols from Tambora caused intense rains across much of Eurasia that caused a blight to grow on grains that contaminated food supplies.
Climate change due to Tambora aerosols caused a drought in India that indirectly led to an outbreak of cholera that then circled the globe.
Crop failures across Europe and the upheaval of the Napoleonic wars led to widespread starvation that made people vulnerable to cholera.
High sulfur concentrations in the surrounding water supplies led to an outbreak of cholera in Indonesia that was spread by ships to other areas.
Food scarcity and the unusually cold conditions that followed the eruption weakened the health of those in poverty, allowing cholera to spread.
